TrustedRoots Swift Reference Documentation
CkoTrustedRoots
Current Version: 10.1.0
Used to set and manage the CA root certificates trusted by your application. This applies to PKCS7 (S/MIME) signature validation and SSL/TLS server certificates.
Object Creation
let obj = CkoTrustedRoots()!
Properties
DebugLogFilePath
If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.
Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.
Possible causes of hangs include:
- A timeout property set to 0, indicating an infinite timeout.
- A hang occurring within an event callback in the application code.
- An internal bug in the Chilkat code causing the hang.
LastErrorHtml
Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastErrorText
Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
LastErrorXml
Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastMethodSuccess
Indicates the success or failure of the most recent method call: true means success, false means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.
topNumCerts
The number of certificates contained within this object.
This is the number of certificates explicitly added by the methods AddCert, AddJavaKeyStore, and LoadCaCertsPem.
topRejectSelfSignedCerts
Indicates whether all self-signed certificates are to be rejected in SSL/TLS connections. The default value of this property is false.
Note: This is for the case where the server certificate chain of authentication is 1 certificate long (i.e. the TLS server certificate itself is self-signed).
topTrustSystemCaRoots
Indicates whether the operating system's CA root certificates are automatically trusted.
On a Windows operating system, this would be the registry-based CA certificate stores. On a Linux system, this could be /etc/ssl/certs/ca-certificates.crt, if it exists. The default value is true. Set this property equal to false to prevent Chilkat from automatically trusting system-provided root CA certificates.
VerboseLogging
If set to true, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is false. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

Methods
Activate
Activates this collection of trusted roots as the set of CA and self-signed root certificates that are to be trusted Chilkat-wide for PKCS7 signature validation and SSL/TLS server certificate validation.
AddCert
AddJavaKeyStore
Adds the trusted certificates from a Java key store to the collection of trusted roots.
Returns true for success, false for failure.
AddJavaKeyStoreAsync (1)
Creates an asynchronous task to call the AddJavaKeyStore method with the arguments provided.
Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.
Returns nil on failure
topDeactivate
Deactivates a previous set of activated trusted roots so that all roots / self-signed certificates are implicitly trusted.
Returns true for success, false for failure.
topGetCert
Returns the Nth cert contained within this object. The 1st certificate is at index 0.
Returns nil on failure
LoadCaCertsPem
Loads a CA bundle in PEM format. This is a file containing CA root certificates that are to be trusted. An example of one such file is the CA certs from mozilla.org exported to a cacert.pem file by the mk-ca-bundle tool located here: http://curl.haxx.se/docs/caextract.html.
Note: This can also be called to load the /etc/ssl/certs/ca-certificates.crt file on Linux systems.
LoadCaCertsPemAsync (1)
Creates an asynchronous task to call the LoadCaCertsPem method with the arguments provided.
Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.
Returns nil on failure
topLoadTaskCaller
Events
To implement an event callback, your application would define and implement a class that inherits from CkoBaseProgress. Your application can implement methods to override some or all of the default/empty method implementations of the CkoBaseProgress base class.
For example:
class MyTrustedRootsProgress : CkoBaseProgress {
override func ProgressInfo(name: String!, value: String!) {
// application code goes here...
print(name + ": " + value)
}
override func AbortCheck(abort: UnsafeMutablePointer) {
// application code goes here...
// To abort the operation, set this equal to true instead of false.
abort.memory = false
}
override func PercentDone(pctDone: NSNumber!, abort: UnsafeMutablePointer) {
// application code goes here...
print(pctDone)
// To abort the operation, set this equal to true instead of false.
abort.memory = false
}
// For asynchronous method calls.
override func TaskCompleted(task: CkoTask!) {
// application code goes here...
}
}
func someAppFunction() {
// Demonstrate how to set the event callback object...
let trustedroots = CkoTrustedRoots()
let myTrustedRootsProgress = MyTrustedRootsProgress()
trustedroots.setEventCallbackObject(myTrustedRootsProgress)
// ...
// ...
// ...
}
AbortCheck
Provides the opportunity for a method call to be aborted. The AbortCheck event is fired periodically based on the value of the HeartbeatMs property. If HeartbeatMs is 0, then no AbortCheck events will fire. As an example, to fire 5 AbortCheck events per second, set the HeartbeatMs property equal to 200.
PercentDone
Provides the percentage completed for any method that involves network communications or time-consuming processing (assuming it is a method where a percentage completion can be measured). This event is only fired when it is possible to know a percentage completion, and when it makes sense to express the operation as a percentage completed. The pctDone argument will have a value from 1 to 100. For operations (Chilkat method calls) that complete very quickly, the number of PercentDone callbacks will vary, but the final callback should have a value of 100. For long running operations, no more than one callback per percentage point will occur (for example: 1, 2, 3, ... 98, 99, 100).
The PercentDone callback counts as an AbortCheck event. For method calls that complete quickly such that PercentDone events fire, it may be that AbortCheck events don't fire because the opportunity to abort is already provided in the PercentDone callback. For time consuming operations, where the amount of time between PercentDone callbacks are long, AbortCheck callbacks may be used to allow for the operation to be aborted in a more responsive manner.
The abort output argument provides a means for aborting the operation. Setting it to true will cause the method to abort and return a failed status (or whatever return value indicates failure).
ProgressInfo
A general name/value event that provides information about what is happening during a method call. To find out what information is available, write code to handle this event and log the name/value pairs. Most are self-explanatory.
TaskCompleted
Called in the background thread when an asynchronous task completes.
